Can a watermark be removed?

1 Answer

Digimarc does not provide tools or software to remove its watermarks. While it is theoretically possible for someone to engineer a Digimarc removal system, the process is asymmetric. By this we mean that removing a Digimarc watermark without discernibly altering the image quality is a difficult process. Because watermarks cannot be removed, we suggest that the image creator/owner retain an original copy of the unwatermarked image. Digimarc’s Readers can read the watermark after scale changes of as much as .6x to 2x of the original image size. A Digimarc watermark can also survive any amount of image rotation.
